cantata-plugin repository transfter

[jlarfors]

@deepuchakram we are having an issue transferring ownership of plugins. We have moved the cantata-plugin to the jenkinsci user (https://github.com/jenkinsci/cantata-plugin) and when we deleted our verifa/cantata-plugin repository the default fork became your repository (deepuchakram/cantata-plugin).

Can we ask you to delete your fork of the cantata-plugin? You can re-create it afterwards
